lMPROVEMENT IN ATTACHMENTS TO STREET-HVDRANTS.

Specification forming part of Ltters Patent No. 163,425, dated May 18,1875 application filed April 2, 1875.

To all whom it may concern:

Be it known that I, CHARLES M. VERGNES, of the city and State of NewYork, have invented an Attachment to Street-Hydrants, of which thefollowing is a specification:

The'object of my invention is to prey'eut street-hydrants from freezing,by an attachment so arranged that during the cold weather they may beempty, when they are not in actual use, and in no way interfering withtheir action at other times.

Figure 1 represents the hydrant now in general use, with my attachmentapplied to it. Big. 2 is the perspective View of the plug and section ofwaste-pipe. Fig. 3 represents the working of the attachment by themotion of the main screw of the hydrant. Fig. 4 shows the catch by whichthe attachment is.used or dispensed with when required.

WVhen the main screw A, Fig. 1, raises the valve B to its highestcapacity, the hydrant is closed, and the cross-piece O G rises, also.The catch D, being closed, raises the small rod R R by means of the headF, and consequently opens the waste-pipe G, causing the water in thehydrant to escape, either into the sewer or a small tank without abottom, where it will be gradually absorbed by the earth. Thecross-piece (J C does not turn with the main screw, but slides up anddown, following the guides H H. The rod R R is furnished with a solidcylinder, S, which. applies to the diaphragm K K, shutting the hole L,through which the rod RB. passes when the sliding piece 0 G presses uponit, thus avoiding the necessity of furnishing the hole L with a boxingapparatus. The cylinder S also acts as a Weight in the fall of the rod RB. At the opposite side of the cylinder, fixed to the diaphragm K K, isa block, M, ot' the same altitude, supporting the cross-piece G G in ahorizontal position when at its lowest point.

The foregoing arrangement shows that during the winter, when the valveBis closed the wastepipe is open and the hydrant becomes empty. Insummer, by opening the catch D, as in Fig. 4, the hydrant will remainfull, the rod R It being free.

What I claim as my invention is The arrangement of the rod R R with thecylinder S, put in motion by the main screw A, and the catch 1),regulating the action of the waste-pipe G, substantially as described.
